Abstract
The present invention relates to a method and arrangement for determining stresses in a spoken sequence. From a sequence recognized in the spoken speech, a model of the speech is created. By comparing the spoken sequence with the modelled speech, a difference between them is obtained. The difference is utilized partly for correcting the modelled speech and partly for determining stresses in the spoken sequence. After having determined the stresses in the speech, it is possible to determine the meaning of individual words and sentences in an unambiguous manner. This is then utilized in different contexts, for example when translating a first language to a second language whilst retaining meaning and intonation. The invention can also be used in verbal man-to-machine communication.
